Description
When heavily using the Gobi2000 ofono runs out of CID (client ids) which means it can not communicate anymore with the modem.
The reason for running out of CID seems to be ofono is leaking those. (Random guess: when doing the state transistion "Online/Powered true -> Powered false" this happen)
In more recent modems/firmwares the firmware support the Sync QMI command, which releases all previous CIDs.
There is also another "Sync" command via the USB serial protocol, but that one isn't implemented by Linux. It's also unclean if it's supported by Gobi2000 or only more recent firmwares.
